The Emancipation Proclamation
President Lincoln read the first draft of this document to his Cabinet members on July 22, 1862. After some changes, he issued the preliminary version on September 22, which specified that the final document would take effect January 1, 1863. Slaves in Confederate states which were not back in the Union by then would be free, but slaves in the Border States were not affected. Naturally, the states in rebellion did not act on Lincoln's order. But the proclamation did show Americans and the world , that the civil war was now being fought to end slavery.
